Nitronaphthalin. — A was a sample which had been in my 

 collection for some years, and the details of its preparation are 

 unknown. It was distilled in steam, and crystallized twice 

 from naphtha and thrice &c. (A 3 &c.) from alcohol. 



B was a similar sample from the same source. It was 

 purified and fractionated exactly in the same way as A. 



Nitronaphthalin becomes sensibly yellowed by continued 

 exposure to light. It melts with considerable sharpness.
